The purpose of this study is to evaluate the effects on cardiac repolarisation of supratherapeutic doses of AZD3480 compared to placebo in healthy male volunteers, subgrouped as extensive metabolisers and poor metabolisers according to CYP2D6 metabolic capacity, using moxifloxacin as positive control.
